EntityFramework Reverse POCO Code First Generator
Beautifully generated code first code that is fully customisable
- Downloadable VSIX installer from the visual studio gallery.
- Watch the in-depth course at pluralsight I cover everything this generator can do, and show you step-by-step how to reverse engineer your database properly.
Reverse engineers an existing database and generates Entity Framework Code First Poco classes, Configuration mappings and DbContext.
Please note, this is not the Microsoft reverse generator. This is one I created to generate beautiful code-first code, as if I had hand-crafted the code-first code myself. It also allows me to customise the generated code to my liking.

Editing TT (T4) Files
To have full syntax highlighting and intellisense when editing TT files, I use the Resharper plugin ForTea. I can't imagine editing TT files without it.
Getting a pull request accepted
Have a read of [https://github.com/blog/1943-how-to-write-the-perfect-pull-request](How to write the perfect pull request)
My requirements are simple:
- Always keep the changes to a minimum, so I can see exactly what's changed in regard to the pull request. I.e. No whitespace tidy up, etc.
- No tabs, only spaces (4).
- Don't move functions about, please leave them where they are.
- No new files. This will always get rejected. Add any new code/classes into the two existing .ttinclude files.
- Don't be tempted to do a few different enhancements in one pull request. Have one pull request for one bug fix / enhancement.
